CARPET-STRETCHER.

SPECIFICATION forming part of Letters Patent No. 431,488, dated July 1,1890.

Application filed March 10,1890. Serial No. 3%,352- (No model.)

To all whom it may concern:

Be it known that I, CHARLES SACK, a citizen of the United States,residing atLebanon, in the county of Laclede and State of Missouri, haveinvented certain new and useful Improvements in Carpet-Stretchers; and Ido hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters of referencemarked thereon.

This invention relates to certain new and useful improvements incarpet-stretchers;

and it has for, its object, among others, to provideap'iimproved deviceof this character, which shall be simple,-d urable, and efficient.

The novelty in the present instance resides in the peculiarities ofconstruction and the combinations, arrangement, and adaptation of parts,all as more fully hereinafter described, shown in the drawings, and thenparticularly pointed out in the appended claim.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and in which- Figure l is a side elevation of acarpetstretcher constructed in accordance with my invention. Fig. 2 is atop plan of the same with parts broken away to better show theconstruction. Fig. 3 is a vertical cross-section.

Like letters of reference indicate like parts throughout the severalviews.

Referring now to the details of the drawin gs by letter, A designatestwo bars arranged parallel to each other and provided along theiradjacent edges with a groove a, as shown in Figs. 2 and 3. I

B is a head or cross piece securely affixed to the bars A and furtherbraced by the diagonal brace-arms b, as shown in Figs. 1 and 2. Upon theunder side of this crosshead is a plurality of sharp-pointed pins oranalogous devices 0, inclined, as shown in Fig. 1, for the purpose ofengaging and holding the carpet when the device is in use. The oppositeends of the bars A are connected by the metallic cross-bar O, secured tothe upper faces thereof in any suitable manner.

D is a bar, preferably somewhatwider than the bars A and provided uponits edges with ribs cl, which work in the grooves of the said bars A, asshown in Figs.2and 3. end of this central bar D is provided with ametallic sleeve or thimble E, as shown in Figs. 1 and 2, and adapted toreceive abar F, as indicated by dotted lines in said figures, the saidbar in use being of a length to reach. to the opposite side of the room,the resistance being the opposite wall. This bar F may be in a singlepiece or of several pieces,'so as to be extensible. The central bar D isprovided with two upright bearings f, provided with lugs e at theirforward ends, and in these bearings is j ournaled the cross-shaft G,upon the ends of which is the cog-wheel g, which meshes with theparallel racks H 011 the bars A, the said racks being set into the saidbars, as shown in Fig. 3, and secured in any suitable manner. Fast onthe shaft G, centrally thereon, is a larger ratchet-wheel I.

J is a lever sleeved on the shaft G and formed with lugs h,between whichis pivoted the dog or pawl 11, as shown in Fig.1, the said pawl having ahandle j, beneath which is arranged a fiat spring K, as shown in saidFig. 1, and acting to at all times keep the pawl in engagement with theratchet-wheel.

Between the lugs e of the bearings f is pivoted the retaining-catch L,adapted also to engage the ratchet-wheel and prevent back movement ofthe parts, as will be readily understood.

The operation is simple and apparent. The extension is fitted in thethimble E and reaches to the opposite side of the room forordinary-sized rooms, allowing about eight inches between the cross-headand the wall. The pins will engage the carpet, and by operating thelever the head and side bars are propelled forward and the carpet isdrawn toward the wall the required amount, when it can be tacked inplace. After the carpet is secured the head is then thrown back, firstdisengaging the retaining-catch. By holding the lever and ratchet-pawland pushing on the cross-head it is again ready for use.

A carpet-stretcher constructed as above described will always be readyfor use, and will be found to have sufficient power to stretch heavycarpets without breaking under severe Strains.

The outer What I claim as new is p In a carpet-stretcher, thecombination, with the outer parallel bars and the cross-head thereon, ofthe central movable bar, the bear- 5 ings thereon, the shaft journaledin said bearings, the cog-Wheels on the ends of the shaft, theratchet-Wheel arranged centrally on the shaft, the lever sleeved on theshaft and formed with ears, the pawl pivoted between I0 said ears andprovided with a handle, the

' spring on the lever beneath the said handle,
